[Kaguya Hime] Maetel Story 4 (Galaxy Express 999)

Big breasts (巨乳, kyonyu) is one of the most iconic body-type tags in doujinshi and manga. It refers to female characters with notably large, exaggerated breasts that often serve as a central visual element. Artists typically emphasize size, weight, jiggle physics, cleavage, and breast-focused activities like paizuri (titjobs) and breast play. This tag spans nearly every genre — from vanilla romance to hardcore fetish content. The artistic treatment varies widely: some artists favor realistic proportions while others push into exaggerated territory. Related body-type tags include 'huge breasts' for extreme cases, 'small breasts' for the opposite aesthetic, and 'paizuri' for breast-focused sexual acts. The tag often appears alongside 'sole female' and 'nakadashi' in heterosexual content.

Shotacon (ショタコン) refers to content featuring young or young-appearing male characters. The term originates from 'Shotaro complex' (after the character Shotaro from Tetsujin 28-go). In doujinshi, this tag indicates the presence of youthful male characters in suggestive or explicit scenarios. Content ranges from innocent to explicit and is a significant demographic category. The tag is the male counterpart to 'lolicon' and often appears in yaoi (male-male) content or in heterosexual scenarios with older female partners.

Mosaic censorship (モザイク) refers to the pixelation or blurring applied to explicit content in Japanese published works. This is due to Japanese obscenity laws that require censorship of genitalia in published materials. The tag helps readers identify whether content is censored or uncensored. Many doujinshi are published with mosaic censorship and later 'decensored' by fans or released in uncensored versions by the artist. Related tags include 'uncensored' and 'full censorship.'
